8 Claims. (Cl. 1607-479) This invention relates to window ventilators and has especially in View certain new and useful improvements therein, whereby the same may 'be readily tted to any size window casing, and which is so constructed that it will not interfere with the raising or lowering of the window to regulate the volume of air admitted to a room, and at the same time will serve as a screen to prevent the entrance of rain, snow, or the like.

The main object of my invention is to provide a ventilator which has means that serves the dual function of providing ventilation and filtering of the air admitted thru the ventilator, filtering from the air such foreign matter as soot, dust and the like, thus actually air-conditioning the room by admitting only clean, pure and fresh air.

Another object of my invention is to provide a Ventilating means which also furnishes the added function of ltering the air admitted into a room, and the said filtering means providing a double filtering action so as to admit the purest and freshest air into a room provided or equipped with my invention.

Another object of my invention is to provide ventilator and filtering means retaining brackets which are readily attachable to and removable from a window casing, so as to faciiltate their attachment or removal during the different seasonal periods of the year.

Another object of my invention is to provide a simple, practical structure, useful for the objects and purposes heretofore mentioned, eilicient in its operation, rigid in structure, and of such simple elements and assembly as to warrant economical manufacture in quantity production.

Other objects and features of my invention -will become apparent from the accompanying drawing, and the ensuing description, in which like numerals are used to designate like parts and in which:

Fig. 1 represents an enlarged fragmentary longitudinal cross-sectional view of that portion of a window showing my invention in place ready for actual use and operation.

Fig. 2 is a front elevation of my invention as it should be positioned facing the outside of a window.

Fig. 3 is a detailed view partially broken away of the ltering and Ventilating means comprising an essential feature of my invention.

Fig. 4 is a partial transversal cross-sectional 'view on the line 4 4 of Figure 1.

Fig. 5 is a detailed view of the slide fastener o r attaching means which may be utilized in connection with the interchangeable attachment of the iiitering and Ventilating means.

Fig. 6 is an enlarged longitudinal cross-sectional view on the line 5-5 of Figure 2.

Fig. 7 is a slightly modified form of a bracket retaining means to be used in connection with my invention.

Fig. 8 is an end View of the view indicated in Figure 7, shown partially in cross-section in order to bring out the details of construction.

Referring to the -various views wherein like numerals are used to designate like parts, in Figure l, 9 designates a standard window Casing sill, having a lower sash l2 provided with a bottom edge El, which when the window is closed, contacts the surface Eil of the window sill 9, thus sealing the window opening. It can be readily seen that the window sash or frame I2 will operate in the casing without interfering with my invention attached to the said window casing. The numeral i3 designates the window pane, whereas my invention is generally characterized by the numeral iii.

Referring to Figures 2 and 3 I show he retaining brackets designated i5. The brackets are made of sheet metal or other suitable material and are provided with flanges I6 which are used to secure the brackets in place by virtue of the screws I 8.

The brackets are provided with slotted portions I'l on the ange I6, and clearance holes I9 are adapted to clear the heads of the screws i3,

` so that the brackets may be removed by merely loosening the screws i9 without removing them, and sliding the brackets l5 so that the holes i9 clear the heads of the screws I8, thus facilitating removal and resetting whenever occasion ktherefor arises during the annual seasonal periods.

The brackets 45 are provided as indicated in the cross-sectional View in Figure 6, with lips Eil on top and on the bottom. The top lip is for the purpose of securing slidably the top clip member 2i, which isformed as indicated in the view Figure 6, having a U shaped portion 22 adapted to fit slidably over the lip 2i?, and a flange portion 23 bent as indicated so as to provide a smooth edge on the clip at this point.

The top retaining clip 2l and the bottom retaining clp 2i are exactly the same, except that the lower clips 2l are securely attached to the lower lips 2i! of the brackets l5 as shown at 24, and are not slidably connected thereto for reaframe-Work 26 when the fastener 32 is closed* thus securing the filtering means to thefframef Work 26.

It is to be noted, that I provide this structure, a dual filtering means so that the In attaching my device to a window, it may be attached as indicated at Figure 1. The screws are preferably placed at the proper position indicated, and threaded into the casing, then the brackets are slid into place, and the screw-heads brought down to bear on the flanges I6 retaining the brackets firmly and securely in place. After each bracket is attached, the clips 2| indicated at Figure 2, are removed by sliding them oiI the retaining lips of the bracket I5'.' The screen set in place in the brackets, and the clips 2| slid on to the lips 20 to retain the screen firmly in place.

, .Y l [15, byrvirtue of air passes thru the filtering section and must? pass also thru the filtering section 29 before itis actually admitted into the room. The filtering means 29v is shaped approximately like a, pillow case or cover, and iits over the frame-Work 26, being open at one end as at 3|, at which end the fastener means 32 is secured, which may be the slide fastener type indicated, or snap fasteners or hooks and eyes, or any other means which may be used to advantage for holding the v,filtering means ,29 secured to the frame-Work 26. Y

In Figure 4, I 'illustrate details ofthe inven-V tion, audit can be readily seen how the brackets I5 may beremoved by virtue of the slot l1 and the clearance slot i9. l Y ,I Y The dotted portion 25 indicates the frame- Work in another position, which indicates that the device comprising my invention by virtue of the width of the bracket sections l5 Will'iit adjustably within that range, so that the filtering means may beV attached to Windows of various sizes and Widths Within the range of adjustment permitted by the Width of the bracket i5.

Figures '7 and 8 show a slightly modified form of the retaining means for the filtering and ventilating means, and as indicated in Figure', is comprised o-f a bracket 33, which has aU` shaped portion 34 at the bottom, and to which isV secured at the top a retaining bracket 38, which is preferably U shaped, and has a hole drilled therein for securing it pivotally tothe bracket 33 atone of its corners by means of hollowV rivets or grommets. The grommeting machine is` preferably set, so that a tight fitting action will secure the grommet 39, in order that the retaining clip 38 may require some slight force to move it about its fulcrum as indicated by the dotted position in the view Figure 7. v Y l The bracket 33 is alsoA provided with a ange 35, which has slots 33, the bracket 33 on the Vfront surface being provided with the screw-head clearance holes 31, in order that the bracket 33 may be attached and removedin like manner asI the brackets illustrated in Figure 2 and Figure 6.

It may be deemed advisable t-o provide indenta- 'tions in the bracket 33, on the side of the retaining clip 38, in order to more firmlysecurethe reltaining clip when it is adapted forfuse ininverted position on top of a window casing toA support the filtering means rigidly. Altho I indioatemin Figure 1 my invention attached to a Windovvcasingat the bottom, it may also be attached at the top of suchawindowcasing. n Y

It goes Without saying, that my inventionma'y be applied to windows of buildings, autom biles, house trailers, aeroplanes, and such other tures utilizing window frame constructionfffor ventilation and air conditioning.

.In like manner, if the bracket in modified form as a retaining means illustrated in Figure 7 and Figure v8 is utilized, the retaining clips 38 are vmerely swung' vvout into upright alignment so as to clear the insertion of the filtering means structure andthen brought down encasing the same and holding it rmly and securely in place.

When it is desired to remove the screen, the

retaining clips 2| arev rotated into the Vdotted position indicated, then theA filtering means maybe fremoved, the fastener 32 is opened allowing the filtering sack 29 `to be remoVed'frOm the frame- Work, and a fresh and cleanviiltering sack applied i The frame-Work after the fastening means 32 is secured in place, is replaced in the Ventilating bracket structure, and is ready for operation and use. The clips 38 are provided with` arounded portion 40 so as to furnish ample clearance for rotation. v,

By virtue of the ltering sack that I provide, it vvill absorb all the foreignsubstances which are injurious, and permeate the air,l and it also provides a ready means of interchangeability of the filtering medium Whenever the case may necessitate. The air admitted will thus be free of pollution and contamination. l

I believe that I have described in rather succinct terms the nature and description of the construction of my invention, lhaving shown a preferred form thereof, and inasmuch as it is susceptible of many modifications, alterations, and improvements, I reserve the right to all such modifications, alterations, and improvements which come Within the spirit and scope of my invention, and Within the purview of the foregoing description and the accompanying drawing; my invention to be limited only by the subjoined claims. i t l A Having thus described and revealed my invention Avvhat I claim asnew and desireY to secure by Letters Patentis:
